PRESSURE-ROLL RELEASE FOR CLOTHES-WRINGERS.

Application filed October 26, 1916.

To all whom it may concern:

Be it known that I, Rm P. -Wrrrorrr, a citizen of the United States, residing at lVashington, in the District of Columbia, have invented certain new and useful Improvements in Pressure-Roll Releases for Clothes-Ringers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in pressure roll release for clothes wringers, and is in the nature of an improvement on an application of John F. Hemenway, for pressure roll release for clothes wringer-s, filed October 2, 1916, Serial No. 1233M. the object being to provide means for normally holding the releasing bars in extended position so that when they have been drawn together out of the keepers in order to release the pressure means by eXerting a downward pressure on the push button, they will automatically return to the extended position when the pressure is released on the push button.

Another object of my invention is to provide a top bar with a spring arranged between the ends of the retaining bars so that the spring will be put under tension when the bars are drawn toward each other in order to force the bars outwardly when the push button is released.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings.

Figure 1 is a side elevation of a clothes wringer showing the application of my improved construction of release thereto;

Fig. 2 is an inverted plan view of a portion of the top bar showing the retaining bars and spring;

Fig. 3 is an end view of the wringer;

Fig. 4 is a detail inverted plan view of the top bar showing a slightly modified form of construction for holding the retaining bars in extended position.

In the drawing I have shown my improved construction of release 'to a clothes wringer composed of a frame 1 having slotted side bars 2 in which are mounted superposed pressure rolls 3 and 4 carried by bearings slidably mounted within the side bars, the upper bearings being provided with spring supports 5 on which are Specification of Letters Patent.

V is provided with'threaded Patented Mar. 20, 1917.

Serial No. 127,898. 7

mounted pressure springs 6 engaged by bearing plates 7 carried by a pressure bar 8. Movably mounted within the slotted portions of the side bars 2, is a 'top bar 9 which boxes 10 adjacent each end carrying pressure screws 11 adapted to engage the bearing plates 7 so as to adjust the pressure on the pressure rolls.

The top bar 9 is provided with guideways 12 in which are mountedretaining bars 13 having substantially T-shaped ends li cooperating with inverted T-shaped slots 15 formed in plates 16 secured to the upper ends of the side bars 2 so as to hold the top bar rigidly within the wringer frame in order to enable the pressure screws to ad just the pressure means. The inner ends of the retaining bars 13 are angled and apertured as shown at 17, and are connected together by a chain 18 which is engaged by the head 19 of a push button 20. slidably mounted within the vertical bore formed in the top bar so that when said push button is forced downwardly, the chain will be carried downwardly in order to draw the retaining bars 18 toward each other.

7 My invention consists in providing means for forcing and holding the retaining bars 13 in extended position, and consists in securing to the under face of the top bar an elongated C-shaped spring 21, the bowed portion of which engages the depending angled ends 17 of the retaining bars as shown in Fig. 2. The spring is preferably secured to the top bar by staples 22 in order to allow the free end portions to yield as the pressure is exerted on the push button so that when the pressure is released on the push button the retaining members will be forced outwardly.

In order to increase the resiliency of the spring for holding the retaining bars in 6X-7 tended position. Ishow a slightly modified form of spring in Fig. 4:, in which the elongated C-shaped spring 23 is provided with a central coil 24 surrounding the shank of the push button, the coil being secured to the under face of the top bar by staples 25.

From the foregoing description it will be seen that I have provided a pressure roll release in which a pair of spring actuated retainin bars are carried by the top bar having substantially T-shaped ends co'riperating with the T-shaped slots of the keepers carried by the side bars so that when the retaining bars are drawn inwardly, the reduced portions of the heads will be brought into alinement with the reduced portions of he slots of the plates in order to allow the top bar to move a predetermined distance upwardly. After the pressure has been released and it is desired to reset the device, by forcing downwardly on the top bar and push button, the retaining bars can be brought into alinement with the enlarged portions of the slots of the plates carried by the side bars so that when the pressure of the push button is released, the retaining bars will be forced into the enlargements of the plates in order to hold the top bar in predetermined position within the Wringer frame.

I claim:

1. A clothes wringer, comprising a frame having pressure rolls and pressure means for said rolls mounted therein, a top bar movably mounted in said frame having means for adjusting said pressure means, retaining bars for holding said top bar in predetermined position within said frame, a spring disposed between said retaining bars for normally holding said bars in set position, a chain connecting the inner ends of said bars, and a push button slidably mounted in said top bar cooperating with said chain for moving said releasing bars in position to release said pressure means.

A. clothes wringer, comprising a frame having pressure rolls and pressure means for said rolls mounted therein, a top bar movably mounted in said frame having means for adjustin said pressure means, keepers carried by the side bars of said frame, slidably mounted retaining bars carried by said top bar cooperating with said keepers for holding said top bar in predetermined posititn within said frame, said retaining bars having angled inner ends, a spring fixed to said top bar between said retaining bars and having portions contacting with the angled ends thereof for holding said retaining bars in extended position, a chain connecting said retaining bars, and a push button mounted in said top bar for depressing said chain for moving said retaining bars in position to release said pressure means.

3. A clothes Wringer, comprising a frame having pressure rolls and pressure means for said rolls mounted therein, a top bar movably mounted in said frame having means for adjusting said pressure means, keepers carried by the side bars, retaining bars slidably mounted on said top bar cooperating with said keepers, said retaining bars having apertured angled inner ends, a substantially ll-shaped spring secured to said top bar having its free end port-ions in engagement With the angled ends of said retaining bars for normally holding said retaining bars in extended position, a chain connecting the angled ends of said retaining bars, and a push button slidably mounted in said top bar cooperating with said chain for moving said retaining bars in position to release said pressure means.

a. A clothes \vringer, comprising a frame having pressure rolls and pressure means for said rolls mounted therein, a top bar movably mounted in said frame having means for adjusting said pressure means, keepers carried by the side bars of said frame, retaining bars slidably carried by said top bar cooperating with said keepers for holding said top bar in predetermined position Within said frame, said retaining )til'S havin angled apertured ends, a chain connecting said angled ends, a substantially S-shaped spring secured to the under side of said top bar having its free end portion arranged in the path of travel of said retaining bars for normally holding said retaining bars in extended position, and a push button slidably mounted in said top bar for depressing said chain for moving said retaining bars in position to release said pressure means.

In testimony whereof I hereunto aiiix my signature.
